Watch: HBO's 'Westworld' whets appetites with Season 2 trailer

'Westworld' star Evan Rachel Wood on how the HBO drama's oppressed androids are an inadvertent metaphor for the Me Too movement.

If you ever wondered what Nirvana's 1993 song Heart-Shaped Box would sound like if it were covered by Ramin Djawadi, the Emmy-nominated composer behind Game of Thrones' hauntingly beautiful scores, Westworld has your answer.

The classed-up grunge classic, whose piano-and-strings arrangement is reminiscent of the piano-driven opening of Thrones' Season 6 finale, serves as the underpinning for the official Season 2 trailer for the HBO series, which returns April 22 at 9 p.m. ET/PT.

The trailer opens and ends with Dolores Abernathy (Evan Rachel Wood) having an existential conversation with Bernard Lowe (Jeffrey Wright), who is responsible for her programming as well as that of the park's other android hosts.

Along the way, we get a taste of the ramifications of last season's robot uprising, which resulted in Dolores murdering Dr. Robert Ford (Anthony Hopkins) and the Delos Corporation trying to contain the damage.

There are is also a revelation or two — or three.

No. 1: This trailer all but confirms the theory that Westworld is an island.

No. 2: We see the return of Hector (Rodrigo "Paolo" Santoro, making amends for ruining Season 3 of Lost), who comes to the rescue of Maeve (Thandie Newton).

No. 3: We get a glimpse of a new park, the geisha-filled Shogun World.
